Part A How far short of the target should it drop the package? Express your answer using three significant figures with the appropriate units.

Answer 1

Answer:

d = 771.3m

Explanation:

Let's first calculate the time of flight:

$Yf = Yo+Voy*t-g*t^2/2$  where Voy=0. Solving for t:

$t = \sqrt{2*90/9.8} =4.285s$

Now we calculate the horizontal displacement, wihch is the distance from the target to drop the package:

Xf = d = Vox*t

d = 180*4.285 = 771.3m
